SUGAR LAND, Texas (KTRK) -- A family is grieving after four people, including three children, died in a house fire in Sugar Land overnight.
Officials with the Sugar Land Fire Department say a house fire call came in around 2:15 a.m. Tuesday on Vista Lakes near Edgewater.
When firefighters arrived, they found fire shooting out of the front door and window of the home. They say the home was completely engulfed.
Firefighters say four individuals died: a grandmother and her three elementary-age grandchildren.
Firefighters also treated the mother of the children and a neighbor for burns.
Officials say social media posts indicate that the family was using a fireplace to stay warm and may have also been using candles.
Officials do not yet know what exactly caused the fire. The Fort Bend Fire Marshal is investigating at the scene.
EDIT: Officials originally reported that the father of the children was killed in the fire, but later corrected that the children's grandmother was the adult killed.
